Abstract


In this paper, we introduce the camber changing mechanism used to produce the flapping force of the hydroplane in a flapping-type turbine. The turbine extracts the power from tidal current that acts to the hydroplane. The magnitude of the force depends on the hydrodynamic characteristics of the hydroplane. The estimated hydrodynamic characteristics for the cambered wing were numerically calculated using the Xfoil software and used to modify the dynamic model formulated for a rigid wing system. The modified mathematical dynamic model was used to predict the flapping response of the variable camber wing. The predicted response was compared with the response of the rigid wing. By using this prediction, we could understand the behavior of the variable camber wing system.
